Take advantage of the -70% downside when this is already a good opportunity. If you still hope for another decrease in the price of 8k-10k, that is each person's choice. But a price that low is still too far for now, unless the market is really not doing well and lots of FUD require bitcoin to collapse again...
Many would like to see not 70%, but 95%. But the reality is that bitcoin, unlike most altcoins, cannot lose such a percentage of its value. And if this really ever happens, then it will be possible to say that this is a complete collapse of the cryptocurrency market.
The things are getting better now, and this morning when market opened green and bitcoin price increased about 2%, it is now trading at $17223 which is above its pivot point(16,818) on weekly chart. This is a sigh of relief for all Bitcoin traders who make their living by trading in crypto. If this trend continues, Bitcoin breaks its next resistance at 18,800, and CPI report comes in line with market expectations, then Bitcoin is likely to close above 20K by the end of current week.
